Getting wisdom teeth taken out? anyone with experiences? 16 years old.?

I'm not really nervous at all. Im getting novocaine and laughing gas so I suppose I won't feel anything. But I got midterms this week so I kind of want to know how many days I'm going to be out. I'm getting it pulled out Wednesday so would I be able to go back by Friday at least? And what kind of prescription did they prescribe you? And how long did the swelling last? Lastly, what did you eat for couple days?
